In the original Japanese lyrics, various words and phrases (including the entire title) are written entirely in katakana where they normally wouldn’t. The effect of this? I’d describe it as adding dynamics to the constant feel of the song’s pace. Maybe something like ripples in a fast-moving stream.

Sasaki Eri, who wrote her own lyrics for this song, has said that the lyrics draw on some of her personal feelings, and that the song is set around her school days in Kyoto (probably university).

I wonder, who decided what “normal” is?
Shit doesn’t matter.
I just want to feel a reality
Greater than “imagination”.

Each and every person is a nameless conductor.
You won’t find anyone anywhere who’s the same as someone else – we’re all special.
When our personalities clash with each other,
＜Pulsating Sequence, Escalating Audience＞
We’re swallowed by the music. This sensation… Ah!!!

Note: the romanized title could in fact be “Yakusoku ~Boku no Shi~” (with the same meaning), but ever since AIR and “Tori no Uta”, I guess I feel entrained to use ‘uta’. I unfortunately can’t find any reliable sources to confirm, so for the moment, I go with my instincts.
